First look video: Meet the couples on The Block All Stars in 2013

The Nine Network's massively popular competitive home renovation show, The Block, is back in 2013 – and this time we’ll see the return of the most popular couples in the series' history.

In the first teaser above, the "not-so-fat tradies" Mark and Duncan (dressed like Mario and Luigi) are back. The pie warmer's been ditched, and the fan favourites believe they "know what colours are in this time. The others better be afraid."

Joining them are Josh and Jenna, Amity and Phil, and Dan and Dani. Will Sydney's favourite celebrity tradies win out?

The Block All Stars returns to Nine Network next year - though no specific date has been announced. Stay tuned!
